Thepin I then is disposed in the wide'portion of thecamslot H? and the shaft E is free to rotate relative to the handle. The handle then is rotated about.

the pivot pin D in a direction to cause the fiat side of the block E to. exert pressure against the cover flange, so that by continued rotation of the handle the cover is forced off ofthe can, the shaft E rotating withrespect to the sleeve H during this'operation to permit the flat side of the block E toremain in flat engagement with the edge of the cover flange whereby'injury to the cover is avoided.

While I haveillustrated and described a preferred construction for carrying my invention into effect, this is capable of varia tion or modification withoutdepartingfrom the spirit of the invention.

to avail myself'of such variations and modifications as come within the scopeof the appended claims. 7

..Having thus described my invention, I

, claim as new and desire to secure by Letters i bar mounted thereon, and a resistancebloclr,

Ifthe can is provided with a label, the blade C may be e I therefore do, not wish to be limited to the exact details of construction herein set forth but desire spring mounted on said handle so as to normally extend from said handle a greater distance than said pointed bar, adaptable under pressure to recede within said handle and to turn in its mounting so that a flat side thereof constantly bears against an object against which it is placed.

2. A lifter for container covers comprising a handle, a bar projecting from said handle for engagement with a covered container to form a pivot on which the handle is adapted to be turned, and a block carried by said handle and having a flat side .for engagement with an edge of the cover to be lifted, said block being rotatably mounted with respect to the. handle so that as the handle is turned on its pivot to pry the .cover from the 0011'- tainer continuous contact of the flat side of said block with the edge o'f'the cover is maintained.
